FIELD OF TECHNOLOGY

Certain embodiments of the disclosure relate to a television contentpackaging and distribution system. More specifically, certainembodiments of the disclosure relate to a method and system forpublishing a disparate live media output stream that complies withdistribution format regulations.

BACKGROUND

The past decade has witnessed a massive expansion of live web simulcastservices in the field of advertisement-based broadcasting and cablenetworking systems. Broadcasting platforms usually refer to types ofnetworks that are used to deliver media content to viewers. Currently,all the broadcasting platforms, such as analog terrestrial broadcast,digital terrestrial broadcast, direct-to-home satellite broadcast,cable, Internet Protocol (IP), and over-the-top television (OTT),compete and strive to increase their appeal in order to gain wideraudience.

Modern web streaming protocols, such as HTTP Live Streaming (HLS) andDynamic Adaptive Streaming over HTTP (DASH), are implemented to supportstreaming of live content services, such as DIRECTV NOW^(SM), SLINGTV^(SM), and PLAY STAYIONT™ VUE, to consumer devices. Traditionalservice providers, such as COMCAST^(SM), also have set-top boxes capableof receiving both legacy broadcast distribution protocols, as well asmodern web streaming protocols. However, such traditional serviceproviders are constrained by the number of broadcast channels they cansupport on the legacy infrastructure and are more likely to allow moreniche-based programming using Internet-based distribution.

Technically, such modern web streaming protocols break media contentinto numerous small broadcast content segments, typically less than 10seconds in length. Modern web streaming protocols further implement amanifest that corresponds to a dataset that may instruct a media playerwhat broadcast content segments to retrieve and play next.

Such modern web streaming protocols further support pre-encoded mediaassets, such as video-on-demand (VOD) assets, and live input streams,such as live media content, as well. The VOD assets prepared for webdistribution may have a sequence of short duration video segments aswell as a pre-encoded media asset manifest. The sequence may includeseparate physical files or pointers (real or to be calculated) to theshort broadcast content segments inside a larger file. The pre-encodedmedia asset manifest may list all the video segments that make up thefull length of the pre-encoded media asset. Alternatively, thepre-encoded media asset manifest may include instructions for the mediaplayer to be able to determine all the video segments of the pre-encodedmedia asset.

On the other hand, in the case of live input streams, new short livebroadcast content segments may be made available as soon as they arecreated. In some protocols, each new short media content segment isadded to a live input stream manifest while in others the media playeris provided necessary information to calculate the next live mediacontent segment. In the latter case, a signal in the live media contentsegment is used to inform the media player to re-inspect the live inputstream manifest for a change in the live media content segment.

The pre-encoded media asset manifest, the live input stream manifest,and/or the broadcast content segments (in the pre-encoded media assetand/or the live input stream) may also include and/or specify additionalinformation to facilitate the media player to transition smoothlybetween media content streams from different sources. The manifest maybe used for creating a playlist of multiple media content files, or forinterrupting media content stream with advertising and then resuming themedia content stream.

Typically, in the broadcast industry, production control systems areutilized to allow an operator to switch between live input streamsreceived from live sources, play pre-encoded media assets, such as VODassets, insert and trigger non-programming content, and insert graphicaltreatment, such as network and program rating bugs. Further, for sourceswithout embedded closed captions, the production control systems alsosupport providing an audio feed to an operator, such as a stenographer,for creation and insertion of the closed captions. The output of suchproduction control systems are referred to as a fully produced feedready for distribution.

However, such production control systems require the live sources to beaggregated at a central location, so that the production control systemscan decode corresponding live input streams for processing. Theaggregation and decoding is essential in case of live input streams ascorresponding schedule 111s tend to change owing to various reasons,such as when live events or programs end early or run long. In case ofthe pre-encoded media assets, fast switching may be required between theredundant broadcast air chains in case of a failure. But, this approachis expensive and is therefore suited for such channels that can attractlarge audiences to justify the cost.

Given the trends toward media content distribution using such streamingprotocols, there is required a system to eliminate the need to aggregateand decode the live sources at a central location. Thus, an advancedsystem may be required that reduces the production cost, and alsoprovide enhanced viewer experience to increase viewer appeal in order togain a wider audience.

Further limitations and disadvantages of conventional and traditionalapproaches will become apparent to one of skill in the art, throughcomparison of such systems with some aspects of the present disclosureas set forth in the remainder of the present application with referenceto the drawings.

The media packaging and distribution system 102 may comprise suitablelogic, circuitry, and interfaces that may be configured to execute codethat handles media content comprising audio, video, images, metadata,manifests, and/or other data (embedded and/or externally referenced).The media content may include a video, an audio, a combination of audioand video presentations, and/or embedded or externally referencedmetadata, a combination of multiple-audio, multiple-video, and/orembedded or externally referenced metadata. Accordingly, the mediapackaging and distribution system 102 provides a disparate live mediaoutput stream that complies with distribution format regulations.

In this regard, the media packaging and distribution system 102 mayprovide video programming services to viewers, usually for asubscription fee (such as pay television). The media packaging anddistribution system 102 also handles distribution, for example,multicasting, unicasting, broadcasting, streaming, for one or morechannels to be viewed on one or more of the consumer devices 110 a, . .. , 110 n.

The media packaging and distribution system 102 may be operated by anentity related to handling or distribution of media content, forexample, a broadcast provider or operator, or a network provider ornetwork operator. The entity related to handling or distribution ofmedia content may also be referred to as a content owner, a distributor,a syndicator, a re-distributor, a content aggregator, a search,discovery, or cataloging service provider, or any other entity activelyor passively involved with the distribution, cataloging, or referencingof complete or partial presentations of media content. Throughout thisdocument, the terms broadcast provider or broadcast operator, andnetwork provider or network operator may be utilized to refer to theentity related to handling or distribution of media content,interchangeably. The broadcast provider may handle a single channel or aplurality of channels, or one or more networks. The broadcast providermay be configured to distribute content via one or more platforms, forexample, traditional over-the-air broadcast channels, radio, cabletelevision networks, satellite communication networks, the Internet,and/or other content delivery networks (CDNs). In this regard, thebroadcast provider may be configured to execute code that communicateslinear video feeds (also referred to as a network television feed orbroadcast feed) to the media packaging and distribution system 102. In abroadcast chain, the broadcast provider may receive actual content, forexample, from a production studio, in a serial digital interface (SDI)video interface and/or on a high-definition SDI (HD-SDI) videointerface, process the content, such as insertion of graphics, closedcaptions, preparation of schedule 111, insertion of triggers, and thelike, and final delivery by a broadcasting apparatus. The linear videofeed may be provided as a multi-program transport stream (MPTS) (alsoreferred to as a live video feed) to the media packaging anddistribution system 102, via the network 108. The MPTS may bedistributed over traditional means as the MPTS may receive the scheduleand be made aware of blackouts, show overruns or last-minute showreplacements only. The broadcast provider may be owned by (or associatedto) a broadcast provider or operator, a network provider or operator, ora content provider or operator.

The media packaging and distribution system 102 may receive the MPTS,which includes the signaling content and metadata, from the broadcastprovider based on, for example, current society of cabletelecommunication engineers (SCTE) standards (SCTE-35 and SCTE-224) tocontrol web and regional blackouts, network end of day switching, andadvertisement insertion. For example, the media packaging anddistribution system 102 may be signaled for various blackout types within-band SCTE-35 message. Further, the media packaging and distributionsystem 102 may receive program metadata that specifies certain events oroperations, such as, for example, when to blackout shows. Examples oflegacy distribution system that may be benefitted from the mediapackaging and distribution system 102 may include direct-broadcastsatellite (DBS) providers, cable television (CATV) systems, and otherwireline video providers and competitive local exchange carriers (CLECs)using, for example, IPTV.

The trending datamay indicate an aggregate interest level of a number of users in thesocial networks for a particular media item. For example, a thousand ormore shares, or likes by a number of users may indicate a highly popularmedia item.

In operation, a stream publishing engine (further shown in FIG. 1B) inthe media packaging and distribution system 102 may generate a previewof the live input streams based on a low-latency protocol. The previewmay be generated based on an insertion of a new segment from thescheduled live input stream manifest into a preview manifest of the liveinput streams on an interval not greater than the previous contentsegment duration. The low-latency protocol may be a protocol, forexample the real time streaming protocol (RTSP), may provide significantreduction in latency by simply reducing the size (or duration) ofreferenced media segments through sub-segmentation. Accordingly, the VPCsystem 115 may be configured to generate an updated schedule based onone or more events identified in the preview of the plurality of liveinput streams in real-time. The updated schedule may include one or moretransitions between the plurality of live input streams and theplurality of pre-encoded media assets. For example, an operatorassociated with the VPC system 115 may view the preview of the pluralityof live input streams including listening to the alternative audio andmay update the schedule in real time based on the events in the preview.In accordance with an embodiment, the stream publishing engine may beconfigured to generate a preview stream of the live stream outputmanifest when the closed captions for the live event are requested. Thestream publishing engine may be configured to communicate the previewstream of the live stream output manifest to a machine and/or humancaptioning system. Consequently, the VPC system 115 may be configured togenerate the live captions stream. The segmented caption files in thelive captions stream may be published to the content delivery system160. The caption stream manifest may be delivered to the streampublishing engine to be published along with the other video and audiostreams. The stream publishing engine may be configured to generate thedisparate live media output stream manifest based on manipulation ofmanifests of a plurality of live input streams and plurality ofpre-encoded media assets in accordance with updated schedule.

The content encoder/packager 128 may be configured to publish the one ormore encoded media assets in real-time or near real-time fordistribution, such as web distribution. The content encoder/packager 128may be operable to create “C3” content assets and clips that may be madeavailable before media content rolls out of the stream playout anddistribution system 112. The content encoder/packager 128 may also beconfigured to provide near-real-time redundancy. The resulting convertedoutput, such as one or more encoded media assets, that are generated bythe content encoder/packager 128 may be communicated to the indexing andstorage system 148 which may be communicatively coupled with theconsumer devices 110 a, . . . , 110 n. The content encoder/packager 128may also support a robust interface (e.g. application data interface(ADI)) that defines the on-demand duration of the individual broadcastcontent segments as well as encryption requirements and a service typeto link for ad insertion.

For encoding and the packaging, the content encoder/packager 128 may beconfigured to mark locations of the one or more non-programming contentbreaks and condition the media content such that the locations of theone or more non-programming content breaks are adjacent to boundaries ofthe plurality of broadcast content segments. Based on the media contentmetadata, in case the one or more indicators are not included in thepre-encoded media asset at packaging time, the content encoder/packager128 may be configured to insert the one or more indicators to mark thecredits and overlay graphics locations in the media content.

Once the content encoder/packager 128 has encoded and packaged the mediacontent based on the associated metadata corresponding to the mediacontent assets for media distribution, the content encoder/packager 128may be further configured to generate corresponding media contentmanifests. The media content manifests may correspond to data sets, suchas text-based instruction sets, that may be utilized by the consumerdevice 110 a to determine which broadcast content segments to play andstorage locations of such broadcast content segments. In accordance withan embodiment, the content encoder/packager 128 may be furtherconfigured to add in-band indicators in the media content assets.

Thebroadcast network scheduler 132 may be configured to generate thebroadcast content schedule based on inputs received from the mediacontent metadata storage system 122 and the schedule planning database136. The broadcast network scheduler 132 may be configured to schedulethe programming content based on, for example, desired channel theme,content metadata, content rights, and competitive analysis of whatcompeting programming content is available on other channels.

The traffic system 134 may comprise suitable logic, circuitry, andinterfaces that may be configured to execute code to receive a list ofprogramming content, such as the broadcast content schedule, to beplayed along with the program indicators, such as program start, fromthe broadcast network scheduler 132. The traffic system 134 may furtherdetermine break durations and locations based on media contentconditioning and an amount of time to be filled to hit the start time ofthe next program in the list of programming content. The traffic system134 may further determine what non-programming content, such as ads, toplace based on data, such as historical performance and competitiveanalysis, received from the schedule planning database 136. The trafficsystem 134 may further insert network rules for schedules, such asoverlay graphic schedules, and the like.

In accordance with an embodiment, the traffic system 134 may check fromthe media content metadata storage system 122 about media contentduration and break schedule. Subsequently, the traffic system 134 may beconfigured to determine the duration for each ad break to have theprogram end at the correct scheduled time and have the new program startat the correct schedule time.

In accordance with an embodiment, the traffic system 134 may becommunicatively coupled with the ad/promo campaign manager 114 todetermine what ads and promos are available to be scheduled. The trafficsystem 134 may be configured to schedule all the advertisements toprovide the highest yield based on historical performance. The trafficsystem 134 may further mark the entire ad break for downstreamreplacement on the consumer device 110 a that is capable of individualad targeting. The traffic system 134 may mark individual ads fordownstream replacement if the ads are targeted to specific audiencedemographics or segments, or specific geo locations.

The schedule planning database 136 may comprise suitable logic,circuitry, and interfaces that may be configured to execute code tostore information that may be used by the broadcast network scheduler132 to generate the broadcast content schedule on a channel. Suchbroadcast content schedule results in maximized size and value ofaudience to advertisers. Such information may also be used to schedulenon-programming content that may provide the highest revenue for thechannel. In accordance with an embodiment, the information may definechannel preferences including when and where to display logos and othergraphics.

The content rights storage 138 may store a set of rules governing whenand how media content may be used. For example, when the media contentmay be made available on-demand, if the media content may be madeavailable over the Internet, whether the media content may be used in adisparate live media output stream and the timeframe, or is the userallowed to restart the media content when live streamed. The historicalperformance storage 140 may store a set of rules governing historicalperformance of users on the media content. The competitive analysisstorage 142 may store a set of rules governing competitive analysis ofvarious providers. For example, direct-broadcast satellite (DBS)providers, cable television (CATV) systems, and other wireline videoproviders and competitive local exchange carriers (CLECs) using IPTV.The channel preferences storage 144 may store previous media contentselections by users for both live input streams and pre-encoded mediaassets that may be used to personalize and organize the channelpreferences in future.

The indexing and storage system 148 may comprise suitable logic,circuitry, and interfaces that may be configured to execute code toreceive the encoded media assets manifests from the contentencoder/packager 128 and live input streams manifests from the livestream encoder/packager 116.

The content delivery system 160 may comprisenetworks configured for distributing media content to the consumerdevices 110 a, . . . , 110 n. Generally, the term “content,” “metadata,”“media,” and similar words are used interchangeably to refer to any typeof media—audio, videos, datacasts, music, text, images, graphics,articles, still photos, animated photos, moving photos, photo galleries,video galleries, infographics, maps, polls, guest biographies, tweets orother social media, blog posts, and/or the like. The content deliverysystem 160 may be configured to provide a plurality of disparate livemedia output streams to the consumer devices 110 a, . . . , 110 n, via atransport stream, segmented streaming, progressive download, or anyother modes of distributing a multimedia presentation, such as via anover-the-air content delivery/distribution network, a linear contentdelivery/distribution network, a cable content delivery/distributionnetwork, a satellite content delivery/distribution network, an InternetProtocol (IP) based content delivery/distribution network, and/or thelike.

The media storage 162 may be configured to store encoded and packagedmedia assets, pre-encoded media asset manifests, live input streams, andlive input stream manifests for distribution.

The proxy server 164 may comprise suitable logic, circuitry, andinterfaces that may be configured to execute code to communicate withthe consumer devices 110 a, . . . , 110 n. In accordance with anembodiment, the proxy server 164 may receive requests from the consumerdevices 110 a, . . . , 110 n when the consumer devices 110 a, . . . ,110 n generate requests for the Ad decisioning server 106 a uponencountering, for example, an advertisement break tag or an overlay tagin the updated disparate live media output stream. In other words, theconsumer devices 110 a, . . . , 110 n may call the proxy server 164 toinitiate the media stream. At stream set-up, any ad ID and informationfrom the consumer devices 110 a, . . . , 110 n is passed to the proxyserver 164. The proxy server 164 or the media player receives themanifest from the content delivery system 160 and decodes (or detects)the indicators, for example break indicators, for non-programingcontent, such as ads. The proxy server 164 then calls the Ad decisioningserver 106a and replaces the non-programing content media segments orthe filler media segments in the manifest and then delivers the manifestto the consumer devices 110 a, . . . , 110 n along with any data aboutthe ads. In an embodiment, the proxy server 164 may be used for one ormore consumer devices of the consumer devices 110 a, . . . , 110 n wherethe media player is fully controlled by a third party and does notsupport ad insertion. In such embodiment, ad blocking may be reducedwhich usually targets communication between the consumer devices 110 a,. . . , 110 n and the Ad decisioning server 106 a. Further, the proxyserver 164 may replace the pre-encoded placeholder content segments,such as slate content segments, with the advertisement content segmentsreceived from the Ad decisioning server 106 a.

In operation, the broadcast network scheduler 132 may be configured toschedule programming content as a broadcast content schedule, based onvarious broadcast content parameters, such as, but not limited to,desired channel theme, content metadata, content rights, and competitiveanalysis of what competing programming is available on other channels.In accordance with an embodiment, the broadcast content schedule maycorrespond to one or more pre-encoded media assets and/or live inputstreams. The broadcast content schedule may correspond to live inputstreams in case a live event is included in the scheduled programmingcontent. For the live content, the broadcast network scheduler 132 maybe configured to access the content rights storage 138 to determine ifthe live input stream has any geo restrictions. Additionally oralternatively, the broadcast network scheduler 132 may be furtherconfigured to determine if the live input stream should be archived forre-play or made available On-Demand or as pre-encoded media asset. Thebroadcast network scheduler 132 may finalize the broadcast contentschedule of the programming content and transmit the broadcast contentschedule to the content processing system 121 and the traffic system134.

The content processing system 121 may determine whether the scheduledprogramming content, such as a pre-encoded media asset, is available andhas been processed to a correct format for distribution. In accordancewith an embodiment, when the programming content is not available, thecontent processing system 121 may order the programming content.Accordingly, the content processing system 121 receives the programmingcontent, assures the quality, and processes the programming content to aspecific standard. The content processing system 121 may further storethe processed programming content as media content asset in the mediacontent master storage system 124. The content processing system 121 mayfurther store the associated metadata in the media content metadatastorage system 122.

In accordance with an embodiment, when the content processing system 121determines that the scheduled programming content, such as a mediacontent asset, is available in the media content master storage system124, the master media content asset is retrieved from the media contentmaster storage system 124. Further, metadata, such as media contentasset duration and the location of non-programming content, such as adbreaks, credits, overlay opportunities, may be determined. Accordingly,the content encoder/packager 128 may be configured to encode the mediacontent asset and packaged for web distribution. During encoding andpackaging, the content encoder/packager 128 may mark the precise adbreak locations and condition the media asset, such that the ad breaklocations fall on boundaries of media segments of the media contentasset.

Further, the content encoder/packager 128 may insert tags to mark thecredits and the potential overlay graphics locations in the mediacontent asset. Additionally, the content encoder/packager 128 may encodeand package one or more high quality profiles to support variousbroadcast use cases. Thus, the content encoder/packager 128 may encodeand package the media content asset for web distribution. The mediacontent asset is thus prepared for the web distribution and hereinafterreferred to as pre-encoded media asset. The pre-encoded media asset andthe corresponding manifest may be stored in the media storage 162 of thecontent delivery system 160.

The traffic system 134 may access the media content metadata storagesystem 122 to determine media content asset duration and break scheduleand generate a schedule 111. The traffic system 134 may furtherdetermine the duration for each ad break to have the program end atcorrect scheduled time and have the new program start at the correctschedule time. In accordance with an embodiment, for live programs, anassumed number of ad breaks with different durations may be programmedbut the exact time of the ad breaks or the duration may not be known.

In accordance with an embodiment, the ad sales team may provide sold adcampaigns and internal promotional campaigns information into thead/promo campaign manager 114. The ad sales team may further provide awindow for the campaigns along with desired audience demographics andsegments, and ad versions.

The traffic system 134 may further communicate with the ad/promocampaign manager 114 to determine what ads and promotional content areavailable to be scheduled. In accordance with another embodiment, thetraffic system 134 may schedule the ads to play to provide the highestyield based on historical performance. The traffic system 134 mayfurther mark an entire ad break for a downstream replacement on aconsumer device, for example the consumer device 110 a, that mayindividually target an ad.

Upon receiving information from the ad/promo campaign manager 114, thecontent processing system 121 may determine whether new non-programmingmedia content, such as the ads and promotional content are entered inthe system 100. The content processing system 121 may further determineif the non-programming media content are already available and has beenprocessed to a correct format. In accordance with an embodiment, whenthe non-programming content is not available, the content processingsystem 121 may order the non-programming content. Accordingly, thecontent processing system 121 receives the non-programming content,assures the quality, and processes the non-programming content to aspecific standard. The content processing system 121 may further storethe processed non-programming content in the ad/promo content masterstorage system 126.

In accordance with an embodiment, when the content processing system 121determines that the scheduled non-programming content, such as ads andpromotional content, is available in the ad/promo content master storagesystem 126, the non-programming content is retrieved from the ad/promocontent master storage system 126. Accordingly, the contentencoder/packager 128 may be configured to encode the non-programmingcontent and package for web distribution. In accordance with anembodiment, the content encoder/packager 128 may further insert in-bandtriggers to identify the ad or promotional content, and provide aspecial instruction for tracking when such on-programming content isviewed. In accordance with another embodiment, the contentencoder/packager 128 may include watermarks or in-band metadata tosupport program viewership measurements in broadcast use cases. Thenon-programming content prepared for web distribution, including themanifest, may be stored in the media storage 162 of the content deliverysystem 160.

For a pre-encoded media asset, the traffic system 134 may leveragechannel preferences to determine when and what network logo to display,when to signal for overlay promotions, and the like. The traffic system134 may generate the schedule 111 and provide schedule 111 to theindexing and storage system 148, the VPC system 115, the Live toOn-Demand toolkit system 117, and the stream publishing engine 150.

In accordance with an embodiment, a live feed may be encoded andpackaged according to defined system specifications and publisheddirectly into the content delivery system 160. Alternatively, for liveevents with limited bandwidth or technical capabilities, the live streambackhaul system 154 may encode a single live stream backhaul feed anddeliver to the central ingest encode/package system 156. At the centralingest encode/package system 156, the single live stream backhaul feedmay be processed and published for web distribution according to thedefined system specifications.

The schedule 111 thus generated may include manifests for live inputstreams and/or pre-encoded media assets, and ads and promotionalcontent, are ingested into the indexing and storage system 148. Inaccordance with an embodiment, a proprietary manifest format may bethere between the content encoder/packager 128 and the indexing andstorage system 148 when additional information carried in the publishedmanifest is required to be passed (not traditionally).

The indexing and storage system 148 may index broadcast content segmentsfrom each manifest corresponding to the live input streams and/orpre-encoded media assets. The indexing and storage system 148 may logindicators indicating ad breaks, program start, program end, graphicoverlays, and the like. The indexing and storage system 148 may furtherperform checks to validate that the live input streams and/orpre-encoded media assets are complete and ready for inclusion in thedisparate live media output stream.

At the schedule time, the stream publishing engine 150 may generate apreview of the live input streams by inserting a new segment from thescheduled live input stream manifest into the preview manifest of thelive input streams on an interval not greater than the previous contentsegment duration. The preview manifest that may address a Group ofPictures or Sub-Group of Pictures inside the media segments to allow astandard web player to operate closer to the live point of the disparatelive media output stream. Alternatively, a custom player may be createdthat may buffer fewer media segments to keep the playback closer to thelive point.

In accordance with an embodiment when all live feeds are backhauled toand encoded and packaged through central ingest encode/package system156, a low latency preview of live input streams may be publisheddirectly to the VPC system 115 from the central ingest encode/packagesystem 156. Such preview of live input streams may include an additionalaudio track, such as the assistant director which often includes acountdown to ad breaks and listing their duration for live events. Anoperator at the VPC system 115 may be configured to view the preview oflive input streams. The operator may further listen to the alternativeaudio and may update the schedule 111 in real-time based on the liveevents in the preview of live input streams.

In accordance with an embodiment, the VPC system 115 may be configuredto insert non-programming content, such as ads, previously defined bythe traffic system 134 as well as a non-programming indicator, such asad indicator, to mark the non-programming when the live event producercalls for an ad break. Further, the VPC system 115 may be configured toinsert the non-programming indicator, such as the ad indicator andfiller content, for the declared break duration. The filler content maybe replaced with targeted ads by the consumer device, for example, theconsumer device 110 a, when the live event producer called for an adbreak.

In accordance with an embodiment, the VPC system 115 may be configuredto switch to an alternate live feed as the scheduled live event endedearly or to get a different perspective of the live event. The VPCsystem 115 may be further configured to start the next pre-encoded mediaasset in the schedule 111 early as the live event ended early. The VPCsystem 115 may be further configured to insert filler program content asthe live event ended early and the next event should be played asoriginally scheduled. The VPC system 115 may be further configured todelay the switch to the next pre-encoded media asset in the schedule 111as the current event is running long or delay the switch to the nextevent in the schedule 111 as the current event is running long. The VPCsystem 115 may be further configured to insert graphical treatment, suchas overlay graphics indicators, and/or programming indicators to signalprogram start and program end for live events in the live input streammanifest.

Accordingly, the stream publishing engine 150 may be configured togenerate a preview of live input streams to the machine and/or humancaptioning system 119 if there is a live event requiring closedcaptions. In accordance with an embodiment, the VPC system 115 mayreceive the captioning data from the machine and/or human captioningsystem 119 and generate a live captions stream. The segmented captionfiles in the live captions stream may be published to the contentdelivery system 160. The caption stream manifest may be delivered to thestream publishing engine 150 to be published along with the other videoand audio streams.

In accordance with an embodiment when all live feeds are backhauled toand encoded and packaged through the central ingest encode/packagesystem 156, a low latency preview of live input streams may be publisheddirectly to the machine and/or human captioning system 119. The captionsdata may be returned and inserted during the web encode.

In accordance with an embodiment, the stream publishing engine 150always checks the schedule 111 before determining the next media segmentto publish. The stream publishing engine 150 may be configured to be oneor more media segments behind any preview of live input streams. Thus,operator at the VPC system 115 is enabled to view the media contentahead of time, decide what should happen next, and update the schedule111 accordingly. Further, time is provided for the captions to be moreclosely synchronized with the audio during live productions.

In accordance with an embodiment, the stream publishing engine 150 maybe configured to generate a disparate live media output stream byinserting a new segment from the scheduled pre-encoded media assetmanifest or the defined live input stream manifest (including theconfigured delay) into the disparate live media output stream manifestoutput on an interval not greater than the previous content segmentduration. When the stream publishing engine 150 encounters indicatorsmarking an ad break within the pre-encoded media asset manifest, in thelive input stream manifest, in the original schedule 111, or added tothe schedule 111 by the VPC system 115, the stream publishing engine 150may insert ad indicators in the disparate live media output streammanifest and stitch in non-programming content, such as ads, promos orfiller content, included in the schedule 111. In accordance with anotherembodiment, when the stream publishing engine 150 encounters indicatorsmarking overlays within the pre-encoded media asset manifest, in thelive input stream manifest, in the original schedule 111 or added to theschedule 111 by the VPC system 115, the stream publishing engine 150 mayinsert indicators in the disparate live media output stream manifestaccording to the schedule 111.

In accordance with an aspect of the disclosure, in case the schedule 111indicates that a live event is to be captured for re-play or to create apre-encoded media asset, the Live to On-Demand toolkit system 117 may beconfigured to capture the live input stream manifest for the definedscheduled time or between the program start and end indictors. The Liveto On-Demand toolkit system 117 may be configured to communicate withthe content delivery system 160 to move the media segments listed in theasset from the network edge. The media segments may be eventually bepurged from the content delivery system 160 and moved to the morepermanent media storage 162 inside the content delivery system 160.

As defined by the schedule 111, the Live to On-Demand toolkit system 117may maintain the ad indicators marking the break locations but removingthe originally scheduled ads or filler content from the archivedpre-encoded media asset manifest. The ad breaks may be deleted, reducedin duration, or extended in duration during playback of the pre-encodedmedia asset or during a scheduled re-play of the live event in thedisparate live media output stream manifest. The Live to On-Demandtoolkit system 117 may be further configured to provide an interface forthe operator to view the archived content and edit the manifest to addor move indicators, remove some media segments, and/or change some ofthe media segments referenced. The interface may be provided in case anad break signal was missed or triggered at the wrong time, the programstart and end is trimmed if the capture was based on time or a start orend trigger was missed, content is required to be removed for somereason and not to be included in the pre-encoded media asset or during areplay of the event, alternative audio segments are referenced withmuted audio in case something was said in the live event that needs tobe removed from the pre-encoded media asset or replay of the event,indictors for the credit start and end to be inserted if not included inthe original event airing, overlay indicators to be inserted or removedif not included or improperly included in the original event airing.

In accordance with an embodiment, the Live to On-Demand toolkit system117 may provide the interface for the operator to, extract, decrypt ifnecessary, and combine into a single file the highest quality profilefor a defined range of media segments that need to be professionallyedited. Accordingly, an operator may then download the combined file oredit the file remotely. The edited file may be submitted through thecontent processing system 121 and moved to the content delivery system160. The edited and processed media segments may be referenced in placeof the original media segments in the pre-encoded media asset for thearchived live content. The final manifest for the archived live inputstream may be ingested into the indexing and storage system 148 if thelive input stream is scheduled for replay.

FIG. 2A illustrates segmentation of live input streams and pre-encodedmedia assets for the schedule 111 for publishing a disparate live mediaoutput stream that complies with distribution format regulations, inaccordance with an exemplary embodiment of the disclosure. Referring tothe exemplary arrangement of FIG. 2A, there is shown a first live inputstream 202, a first pre-encoded media asset 204, and a second live inputstream 206. There is also shown a targeted first interstitial content208 scheduled after the first live input stream 202, and a secondinterstitial content 210 scheduled after the first pre-encoded mediaasset 204. The first live input stream 202 may be segmented into a firstset of video segments 202 a, 202 b, 202 c, . . . , 202 n. Similarly, thefirst pre-encoded media asset 204 and the second live input stream 206may also be segmented into second set of video segments 204 a, 204 b,204 c, . . . , 204 n, and third set of video segments 206 a, 206 b, 206c, . . . , 206 n respectively. By way of example, the segmentation maybe executed by a segmenting system (not shown) during a preparationstage of the media assets. In accordance with an embodiment, thesegments of the first set of video segments 202 a, 202 b, 202 c, . . . ,202 n, the second set of video segments 204 a, 204 b, 204 c, . . . , 204n, and third set of video segments 206 a, 206 b, 206 c, . . . , 206 n,may be segmented into consistent length, for example, 10 secondssegments. It may be advantageous to have a consistent and smaller filesize of segments to be able to quickly push to the content deliverysystem 160, and also for quick downloading by a media player at theend-user side, such as on the consumer device 110 a.

It should be understood by those skilled in the art that various changesmay be made and segments of different file sizes (or length) may be usedwithout departure from the scope of the present disclosure. Further,other streaming protocols may require a different processing of mediacontent. Thus, the scope of the disclosure should not be limited to theprocessing or preparation of media content to allow delivery usingdifferent delivery methods, streaming protocols, or distribution system,known in the art. Further, instead of the live input streams andpre-encoded media asset arranged, as shown, different arrangements perthe schedule 111 may be possible with respect to interstitial contentitems, such as the first interstitial content 208 and the secondinterstitial content 210. In accordance with an embodiment, the firstinterstitial content 208 and the second interstitial content 210 maycorrespond to non-programming content, such as ads or promotionalcontent targeted for the consumer device 110a.

The insertion of the live input stream manifests, pre-encoded mediaasset manifests, the interstitial content items may be done on-the-flybased on dynamic scheduling resulting in the schedule 111. The insertionmay be driven by real-time or near-real-time content context analysis,user-selection on the consumer device 110 a, or driven by external datareceived from the external data source 120. The stream publishing engine150 may be configured to insert live input streams (such as the firstlive input stream 202 and the second live input stream 206), pre-storedmedia assets (such as the first pre-encoded media asset 204), andinterstitial content items (such as the first interstitial content 208and the second interstitial content 210), in the disparate live mediaoutput stream based on manipulation of the disparate live media outputstream manifest for corresponding live channel.

In accordance with an embodiment, each segment of the first set of videosegments 202 a, 202 b, 202 c, . . . , 202 n, the second set of videosegments 204 a, 204 b, 204 c, . . . , 204 n, and third set of videosegments 206 a, 206 b, 206 c, . . . , 206 n, may be further processed tobe stored at various quality levels, and content encryption modes forthe purposes of adaptive bitrate streaming and digital rightsmanagement, for example, the video segment 202 a may be stored in aplurality of quality levels or profiles, for example, high definition(HD), high dynamic range (HDR) video, or different quality levels inaccordance with specified pixel resolutions, bitrates, frame rates,and/or sample frequencies. Each of the media content, such as 202 to206, are encoded, segmented, and stored with the plurality of qualitylevels in the media content master storage system 124. The media contentmay be re-used to create new variant channels, such as a new variant ofthe disparate live media output stream, without having to re-encode aselected live input stream or a pre-encoded media asset when the newvariant of the disparate live media output stream is created by thestream publishing engine 150.

For the sake of brevity, and with reference to FIG. 2A, there is shownan example of publishing the disparate live media output stream based ondynamic insertion of interstitial content items by the stream playoutand distribution system 112 of FIG. 1B. It is to be understood thatmedia packaging for different delivery methods (such as analogterrestrial broadcast, digital terrestrial broadcast, direct-to-homesatellite broadcast, cable, other Internet Protocol (IP)-based deliverymethods, over-the-top television (OTT)), different streaming protocols,or distribution system, may be different. The media content may beprepared to be viewed one or more of the consumer devices 110 a, . . . ,110 n, based on at least the desired delivery method, deliveryconditions, content protection requirements, to satisfy operational andtechnical requirements, as needed. The operational and technicalrequirements may include, but are not limited to, media encoding, mediasegmentation, schedule 111 (or manifest) creation or manipulationrequirements, desired media encryption, and/or metadata signalingrequirements. For example, in certain scenarios and for certain mediacontent delivery methods, network bandwidth, network conditions, ordevice-type where media content is to be consumed may not be variable orknown in advance. In such a case, creating different quality levels forsame media content may not be required. In other cases, for example, thestream publishing engine 150 may exclude the one or more high qualityprofiles provided to support broadcast use cases, or exclude one or moreprofiles created for consumer distribution. In some other cases, thecontent encoder/packager 128 may encode and package one or more highquality profiles to support broadcast use cases or include one or morehigh quality profiles of interstitial content items for the encoded andpackaged pre-encoded media asset to support broadcast use cases.Further, based on different operational and technical requirements,publishing of the disparate live media output stream may be different.As descried above, the media content that is prepared and distributedmay include both the programming content, such as long-formpresentations, short-form presentations, news or sporting events; andnon-programming content, such as paid advertisements, public serviceadvertisements, or promotional material.

FIG. 2B illustrates various exemplary scenarios to virtualize productioncontrol functions, in accordance with an exemplary embodiment of thedisclosure. In order to enable the VPC system 115 to be virtualized bynot being located at the same location, such as a studio, the VPC systemmay be required to receive the live input streams ahead of time. Inaccordance with an embodiment, it may be done through pure manifestmanipulation. In accordance with an embodiment, based on the web ormedia players, the media segments may be of a fixed duration, forexample 10 seconds or 2 seconds long in case of modern web streamingprotocols. A client, for example the first consumer device 110 a, maywant to buffer three media segments before playback is started. Thus,three media segments may be required to be downloaded to be three mediasegments ahead or playback three media segments behind the live point.

In accordance with an embodiment, as described in FIG. 2A andillustrated in block B1 of FIG. 2B, the un-manipulated first live inputstream 202 may be segmented by a first live stream encoder/packager 116a into a first set of video segments 202 a, 202 b, 202 c, 202 d, and 202e. Further, the second live input stream 206 may be segmented by asecond live stream encoder/packager 116 n into a third set of videosegments 206 a, 206 b, 206 c, 206 d, and 206 e. In accordance with theexemplary scenario, a live point may be located after five mediasegments from each of the first and second sets of video segments thatare provided by the content delivery system 160.

Block B2 illustrates manipulated version of the live input streamsgenerated by the stream publishing engine for virtual master previewthat is close to the live point L. Segment set 51 corresponds tostandard player with optimized manifest for delivery of fragmentedmedia, such as byte range references to individual segments. Segment setS2 corresponds to a custom player with a single segment buffer. This maygive a player position (P) one segment behind the live point (L).

Block B3 illustrates manipulated manifests published by the streampublishing engine for consumer delay. Segment set S3 corresponds to ahigher latency mode were the operator previews the segment beforedetermining whether switch should occur or not. Segment set S4corresponds to a lower latency mode where switch occurs based on whatthe operator anticipated in the next segment. ‘Segment 4’ in segment setS3 and ‘Segment 5’ in segment set S4, respectively, are not publishedyet that may correspond to a decision point to perform one of: continuelive input stream, insert ad, insert pre-encoded media asset, or switchto an alternate stream. In case of higher latency mode, player position(P1) is behind ‘Segment 1’ and is three segments behind the live point(L1). Further, in case of lower latency mode, player position (P2) isbehind ‘Segment 2’ and is again three segments behind the live point(L2).

FIG. 3 illustrates an exemplary scenario associated with a disparatelive media output stream that complies with distribution formatregulations by the VPC system 115, in accordance with an exemplaryembodiment of the disclosure. Referring to the exemplary scenario inFIG. 3, there are shown a schedule of live input streams and pre-encodedmedia assets corresponding to defined timestamps generated by thebroadcast network scheduler 132. In accordance with the exemplaryscenario, the Adult Swim live show from Atlanta (Atl) studio may bescheduled from 9:00 am to 10:00 am, live show from Burbank (Brbnk)studio may be scheduled from 10:00 am to 11:00 am, and a pre-recordedmarathon of a show may be scheduled from 11:00 am to 1:00 pm. From 1:00pm-2:00 pm, a replay of the 9:00 am Adult Swim live show from Atlantastudio may be scheduled.

The On-Demand content, for example the pre-recorded marathon of theshow, if not already created, is transmitted to the content processingsystem 121 to get encoded and packaged and delivered to the contentdelivery system 160 before being published. The traffic system 134 maybe configured to determine various duration of ad breaks based onavailable time and preferences. For example, for each hour of thepre-recorded marathon of the show of two episodes (which without ads maytotal upto 42 minutes), the traffic system 134 may determine a durationof 18 minutes of ads and promos to fill up the available time durationof 18 minutes. Thus, the traffic system 134 may be generated theschedule 111 comprising programming content (such as the live inputstreams and pre-encoded media assets) and non-programming content (suchas ads, promos, or filler content) and allow the customer devices insertthe ads through the proxy server 164.

In accordance with an embodiment, as described in FIG. 1B, the scheduledlive events in the live input streams that are fed to the live streamencoder/packager 116, a backhaul version may be added. For example, ifbandwidth is available, live stream encoding and packaging of the liveinput streams from the Atlanta studio and the Burbank studio may be doneat the respective locations to create for example, 9 profiles. However,in live sporting events, in case of insufficient bandwidth, the highestquality feed may be provided to an encoding and packaging location assingle profile, which is the live stream backhaul system 154. Theencoded and packaged single backhaul stream may be ingested to thecentral ingest encode/package system 156, which may be onsite orcorrespond to Amazon®. The central ingest encode/package system 156 mayperform encoding and packaging to required bit rates and specificationsthat are required for the content delivery system 160, which is furthertransmitted to the indexing and storage system 148. The indexing andstorage system 148 may index each segment of the live input streams andpre-encoded media assets. Then the stream publishing engine 150 mayswitch between sources that have segment duration of, for example 2seconds, based on the schedule 111, and accordingly publishes variouslive input streams and pre-encoded media assets as a disparate livemedia output stream “Program out manifest” scheduled per the schedule111. In accordance with an embodiment, the VPC system 115 may update theschedule 111 to insert an ad break for, for example 120 seconds, whichis continuously referred to by the stream publishing engine 150. Forexample, the production director associated with the VPC system 115 maysignal for an ad break of 2 minutes. After 10 minutes, the productiondirector may signal for another ad break.

In accordance with an embodiment, the Atlanta Live show may end at 9:54am instead of 10:00 am. The production director may signal that theAtlanta Live show has ended and the program may be switched for 6minutes to an alternate live feed, for example a camera set upcorresponding to a clock feed. At 10:00 am, program may be switched tothe Burbank Live show. In case not available, filler content may beplayed out. Thus, the VPC 115 has an access to all the programming andnon-programming content and in near-real time may update the schedule111 to switch between different programming and non-programming content.

FIGS. 4A and 4B collectively depict a flowchart illustrating exemplaryoperations for publishing a disparate live media output stream thatcomplies with distribution format regulations by the media packaging anddistribution system 102 of FIG. 1B, in accordance with an exemplaryembodiment of the disclosure.

At 402, a broadcast content schedule may be generated based on aplurality of broadcast content parameters associated with theprogramming content scheduled for a broadcast channel. In accordancewith an embodiment, the broadcast network scheduler 132 may beconfigured to a generate the broadcast content schedule for schedulingthe programming content based on the plurality of broadcast contentparameters, such as, but not limited to, desired channel theme, contentmetadata, content rights, and competitive analysis of what competingprogramming is available on other channels. The broadcast networkscheduler 132 may receive the plurality of broadcast content parametersfrom the content rights storage 138, the historical performance storage140, the competitive analysis storage 142, and the channel preferencestorage 144 in the schedule planning database 136.

The broadcast content schedule may correspond to live input streams incase a live event is included in the scheduled programming content. Forthe live content, the broadcast network scheduler 132 may be configuredto access the content rights storage 138 to determine if the live inputstream has any geo restrictions. Additionally or alternatively, thebroadcast network scheduler 132 may be further configured to determineif the live input stream should be archived for re-play or madeavailable On-Demand or as pre-encoded media asset. The broadcast networkscheduler 132 may finalize the broadcast content schedule of theprogramming content and transmit the broadcast content schedule to thecontent processing system 121 and the traffic system 134.

At 404, broadcast content, in accordance with one or more streamingprotocols to generate a plurality of encoded broadcast content segments,which may be received, encoded, and packaged based on the broadcastcontent schedule. In an embodiment, the content encoder/packager 128 inthe content processing system 121 may be configured to receive, encode,and package broadcast content (or programming content), in accordancewith one or more streaming protocols to generate a plurality of encodedbroadcast content segments, based on the broadcast content schedule.Specifically, when the programming content is not available, the contentencoder/packager 128 in the content processing system 121 may retrievethe programming content, for example, media content asset, from themedia content master storage system 124, assures the quality, andprocesses the programming content to a specific standard.

The content encoder/packager 128 may further insert in-band triggers tomark the location of the ad breaks, credits, and potential overlaygraphic locations for protocols that do not constantly query themanifest for new information but instead calculate the next content tobe downloaded based on a defined algorithm. In accordance with anotherembodiment, the content encoder/packager 128 may include watermarks orin-band metadata to support program viewership measurements in broadcastuse cases. The media content asset is thus prepared for the webdistribution and hereinafter referred to as pre-encoded media asset. Thepre-encoded media asset and the corresponding manifest may be stored inthe media storage 162 of the content delivery system 160.

At 406, the media content metadata storage system 122 may be accessed todetermine media content asset duration and break schedule. In accordancewith an embodiment, the traffic system 134 may be configured to accessthe media content metadata storage system 122 to determine media contentasset duration and break schedule. The traffic system 134 may furtherdetermine the duration for each ad break to have the program end atcorrect scheduled time and have the new program start at the correctschedule time. In accordance with an embodiment, for live programs, anassumed number of ad breaks with different durations may be programmedbut the exact time of the ad breaks or the duration may not be known.

At 408, communication with the Ad/promo campaign manager 114 may beestablished to determine what non-programming content is available to bescheduled. In accordance with an embodiment, the traffic system 134 maybe configured to communicate with the Ad/promo campaign manager 114 todetermine what non-programming content is available to be scheduled. Inaccordance with an embodiment, the ad sales team may provide sold adcampaigns and internal promotional campaigns information into thead/promo campaign manager 114. The ad sales team may further provide awindow for the campaigns along with desired audience demographics andsegments, and ad versions.

In accordance with an embodiment, the traffic system 134 may schedulethe ads to play to provide the highest yield based on historicalperformance. The traffic system 134 may further mark an entire ad breakfor a downstream replacement on a consumer device, for example theconsumer device 110 a, that may individually target an ad.

Upon receiving information from the ad/promo campaign manager 114, thecontent processing system 121 may determine whether new non-programmingmedia content, such as the ads and promotional content are entered inthe system. The content processing system 121 may further determine ifthe non-programming media content are already available and has beenprocessed to a correct format. In accordance with an embodiment, whenthe non-programming content is not available, the content processingsystem 121 may order the non-programming content. Accordingly, thecontent processing system 121 receives the non-programming content,assures the quality, and processes the non-programming content to aspecific standard. The content processing system 121 may further storethe processed non-programming content in the ad/promo content masterstorage system 126.

At 410, the non-programming content may be received, encoded, andpackaged for web distribution. In accordance with an embodiment, whenthe content processing system 121 determines that the schedulednon-programming content, such as ads and promotional content, isavailable in the ad/promo content master storage system 126, thenon-programming content is retrieved from the ad/promo content masterstorage system 126. Accordingly, the content encoder/packager 128 may beconfigured to encode the non-programming content and package for webdistribution. In accordance with an embodiment, the contentencoder/packager 128 may insert in-band triggers to identify the ad orpromotional content and provide special instructions for tracking whenit is viewed. In accordance with another embodiment, the contentencoder/packager 128 may include watermarks or in-band metadata tosupport ad and promotional content viewership measurements in broadcastuse cases. The non-programming content may be prepared for webdistribution and may be stored in the media storage 162 of the contentdelivery system 160. In accordance with an embodiment, for a pre-encodedmedia asset, the traffic system 134 may leverage channel preferences todetermine when and what network logo to display, when to signal foroverlay promotions, and the like.

At 412, the schedule 111 may be generated based on insertion of aschedule for programming and non-programming content in the broadcastcontent schedule. In accordance with an embodiment, the traffic system134 may access the media content metadata storage system 122 todetermine media content asset duration and break schedule and generatethe schedule 111. Thus, the schedule 111 includes the schedule for theone or more non-programming content and/or one or more programmingcontent. In other words, the schedule 111 may include manifests for liveinput streams and/or pre-encoded media assets, and ads and promotionalcontent. In accordance with an embodiment, the schedule 111 for the oneor more non-programming content and the one or more programming contentmay be generated based on the content viewing demographics.

Prior to generation of the schedule 111, as discussed above, the contentprocessing system 121 may determine whether the non-programming mediacontent, such as the ads and promotional content, and the programmingcontent are available and have been processed to a correct format. Inaccordance with an embodiment, when the non-programming content is notavailable, the content processing system 121 may order thenon-programming content. Accordingly, the content processing system 121receives the non-programming content, assures the quality, and processesthe programming and non-programming content to a specific standard. Thecontent processing system 121 may further store the processedprogramming and non-programming content in the media content masterstorage system 124 and the ad/promo content master storage system 126,respectively. Accordingly, the content encoder/packager 128 in thecontent processing system 121 may retrieve the programming content fromthe media content master storage system 124, and the non-programmingcontent from the ad/promo content master storage system 126. The contentencoder/packager 128 may further encode and package the programming andthe non-programming content for web distribution.

In accordance with various embodiments, the traffic system 134 mayprovide the schedule 111 to the indexing and storage system 148, the VPCsystem 115, the Live to On-Demand toolkit system 117, and the streampublishing engine 150.

At 414, a live feed may be encoded and packaged according to the systemspecifications and published directly into the content delivery system160. In accordance with an embodiment, the live stream encoder/packager116 may be configured to encode and package a plurality of live feeds,into a plurality of live input streams, according to the systemspecifications and published directly into the content delivery system160. Alternatively, for live events with limited bandwidth or technicalcapabilities, a single live stream backhaul feed may be encoded anddelivered to the central ingest encode/package system 156. In accordancewith an embodiment, the live stream backhaul system 154 may encode thesingle live stream backhaul feed and deliver to the central ingestencode/package system 156. At the central ingest encode/package system156, the single live stream backhaul feed may be processed and publishedfor web distribution according to the defined system specifications.

At 416, manifests for the live input streams and pre-encoded mediaassets including non-programming content listed in the schedule 111 maybe ingested into the indexing and storage system 148. In accordance withan embodiment, the indexing and storage system 148 may be configured toingest the manifests for the live input streams live feeds andpre-encoded media assets including non-programming content listed in theschedule 111. In accordance with an embodiment, a proprietary manifestformat may be there between the content encoder/packager 128 and theindexing and storage system 148 when additional information carried inthe published manifest is required to be passed (not traditionally).

The indexing and storage system 148 may index broadcast content segmentsfrom each manifest corresponding to the live input streams and/orpre-encoded media assets. The indexing and storage system 148 may logindicators indicating ad breaks, program start, program end, graphicoverlays, and the like. The indexing and storage system 148 may furtherperform checks to validate that the live input streams and/orpre-encoded media assets are complete and ready for inclusion in thedisparate live media output stream.

At 418, a preview of live input streams based on a low-latency protocolmay be generated for a plurality of live input streams. In accordancewith an embodiment, the stream publishing engine 150 may generate apreview of the live input streams based on the low-latency protocol. Thepreview may be generated based on an insertion of a new segment from thescheduled live input stream manifest into the preview manifest of thelive input streams on an interval not greater than the previous contentsegment duration.

The preview of the live input streams that may address a Group ofPictures or Sub-Group of Pictures inside the media segments to allow astandard web player to operate closer to the live point of the disparatelive media output stream. Alternatively, a custom player may be createdthat may buffer fewer media segments to keep the playback closer to thelive point.

In accordance with an embodiment when all live feeds are backhauled to,and encoded and packaged through the central ingest encode/packagesystem 156, a low latency preview of live input stream may be publisheddirectly to the VPC system 115 from the central ingest encode/packagesystem 156. In accordance with an embodiment, the plurality of liveinput streams may include additional audio content that may identifieslocation and duration of a non-programming content for live events thatcorrespond to the plurality of live input streams. For example, suchpreview of live input stream may include an additional audio track, suchas the assistant director which often includes a countdown to ad breaksand listing their duration for live events. An operator at the VPCsystem 115 may be configured to view the preview of live input streams.The operator may further listen to the alternative audio and may updatethe schedule 111 in real-time based on the live events in the preview oflive input streams.

In accordance with an embodiment, the preview for the plurality of liveinput stream may be generated based on a low-latency protocol duringoriginal encode of the live input stream.

In accordance with an embodiment, the the stream publishing engine 150may be configured to provide the generated preview of the plurality oflive input streams that comprises audio content to the machine and/orhuman captioning system 119. The machine and/or human captioning system119 may generate programming content that includes live captions for oneor more non-captioned live events.

At 420, an updated schedule may be generated based on one or more eventsidentified in the preview of the plurality of live input streams inreal-time, wherein the updated schedule includes one or more transitionsbetween the plurality of live input streams and a plurality ofpre-encoded media assets. In accordance with an embodiment, the VPCsystem 115 may be configured to generate the updated schedule based onone or more events identified in the preview of the plurality of liveinput streams in real-time, wherein the updated schedule includes one ormore transitions between the plurality of live input streams and theplurality of pre-encoded media assets. For example, the operatorassociated with the VPC system 115 may view the preview of the pluralityof live input streams including listening to the alternative audio andmay update the schedule 111 in real time based on the events in thepreview.

In accordance with an embodiment, the operator associated with the VPCsystem 115 may mark a beginning and an end of a live event in an indexof the live input streams based on the generated preview. The operatorassociated with the VPC system 115 may include the marked live event inthe at least one of the plurality of live input streams on live or ondelay according to the updated schedule for disparate live media outputstream manifest. Accordingly, the Live to On-Demand toolkit system 117may convert the marked live event in the at least one of the pluralityof live input streams to a pre-encoded media asset of the plurality ofpre-encoded media assets to support one of a replay or a delay of themarked live event to a time beyond when media segments remain availablein a content delivery system and an index of the manifest of the liveinput stream remains in the media storage 162.

In accordance with various embodiments, the generated updated schedulemay indicate insertion of a non-programming content indicator andtrafficked non-programming content for a specified duration of anon-programming content break, and insertion of the non-programmingcontent indicator and filler content for the specified duration of thenon-programming content break which allows a consumer device to replacethe filler content with targeted non-programming content. The generatedupdated schedule may further indicate a switch to an alternate liveinput stream due to one or more of: technical defects, a live eventended on a current live input stream ahead of scheduled time, and/or aprovision of a different vantage point for the live event. The generatedupdated schedule may further indicate insertion of a filler programcontent as a first live event ended before scheduled time and the nextevent has not yet started, and/or a start of the next event ahead ofschedule if the first live event ended early. The generated updatedschedule may further indicate a delay to switch to a next scheduled liveinput stream or a pre-encoded media asset if current live event runs fora time period that exceeds a threshold time period, insertion of agraphical treatment indicator to be inserted at the consumer device,and/or insertion of a programming content indicator to mark a beginningor an end of a live event in the disparate live media output streammanifest.

At 422, a preview stream of the live stream output manifest may begenerated when closed captions for a live event is requested. Inaccordance with an embodiment, the stream publishing engine 150 may beconfigured to generate the preview stream of the live stream outputmanifest when the closed captions for the live event are requested. Thestream publishing engine 150 may be configured to communicate thepreview stream of the live stream output manifest to the machine and/orhuman captioning system 119.

At 424, a live captions stream may be generated. In accordance with anembodiment, the VPC system 115 may be configured to generate the livecaptions stream. The segmented caption files in the live captions streammay be published to the content delivery system 160. The caption streammanifest may be delivered to the stream publishing engine 150 to bepublished along with the other video and audio streams.

At 426, a disparate live media output stream manifest may be generatedbased on manipulation of manifests of a plurality of live input streamsand plurality of pre-encoded media assets in accordance with updatedschedule. In accordance with an embodiment, the stream publishing engine150 may be configured to generate the disparate live media output streammanifest based on manipulation of manifests of a plurality of live inputstreams and plurality of pre-encoded media assets in accordance withupdated schedule.

In accordance with an embodiment, the generated disparate live mediaoutput stream manifest may be delayed to allow decisions based on thepreviewed plurality of live input streams in a disparate live mediaoutput stream. The disparate live media output stream may includeprogramming content and non-programming content available to the one ormore processors for immediate consumption. Further, the disparate livemedia output stream complies with distribution format regulations. Thedistribution format regulations complies with Federal CommunicationsCommission (FCC) standards regarding closed captioning (in case ofbroadcast or Internet streaming), TV ratings, information, markedratings, inclusion and complies with stream owner/operator requirementsfor network logos and identification.

During the generation of the disparate live media output stream, thestream publishing engine 150 may encounter indicators marking an adbreak within the pre-encoded media asset manifest, in the live inputstream manifest, in the original schedule 111, or added to the schedule111 by the VPC system 115. Accordingly, the stream publishing engine 150may insert ad indicators in the disparate live media output streammanifest and stitch in non-programming content, such as ads, promos orfiller content, included in the schedule 111. In accordance with anotherembodiment, when the stream publishing engine 150 encounters indicatorsmarking overlays within the pre-encoded media asset manifest, in thelive input stream manifest, in the original schedule 111 or added to theschedule 111 by the VPC system 115, the stream publishing engine 150 mayinsert indicators in the disparate live media output stream manifestaccording to the schedule 111.

FIG. 5 depicts another flowchart illustrating exemplary operations forpublishing a disparate live media output stream that complies withdistribution format regulations by the media packaging and distributionsystem 102 of FIG. 1B, in accordance with an exemplary embodiment of thedisclosure.

At 502, a live input stream and a manifest of the live input stream maybe captured from one of the content delivery system 160 or the mediastorage 162. In accordance with an embodiment, the Live to On-Demandtoolkit system 117 may be configured to capture the live input streammanifest for the defined scheduled time or between the program start andend indictors. The Live to On-Demand toolkit system 117 captures thelive input stream manifest when the schedule 111 is defined to indicatewhether an event in the live input stream is to be captured for re-playor to create pre-encoded media asset.

At 504, one or more media segments may be referenced in the live inputstream manifest to be moved from an edge of the content delivery system160. In accordance with an embodiment, the Live to On-Demand toolkitsystem 117 may be configured to communicate with the content deliverysystem 160 to move the media segments listed in the asset from thenetwork edge. The media segments may be eventually be purged from thecontent delivery system 160 and moved to the more permanent mediastorage 162 inside the content delivery system 160. p In accordance withan embodiment, as defined by the schedule 111, the Live to On-Demandtoolkit system 117 may maintain the ad indicators marking the breaklocations but removing the originally scheduled ads or filler contentfrom the archived pre-encoded media asset manifest. The ad breaks may bedeleted, reduced in duration, or extended in duration during playback ofthe pre-encoded media asset or during a scheduled re-play of the liveevent in the disparate live media output stream manifest.

At 506, the one or more media segments, referenced in the live inputstream manifest, may be edited. In accordance with an embodiment, theLive to On-Demand toolkit system 117 may be configured to edit the oneor more media segments referenced in the live input stream manifest. TheLive to On-Demand toolkit system 117 may provide an interface for theoperator to view the archived content and edit the manifest to add ormove indicators, remove some media segments, and/or change some of thereferenced one or more media segments.

The interface may be provided in case an ad break signal was missed ortriggered at the wrong time. The program start and end may be trimmed ifthe capture was based on time or a start or end trigger was missed.Content that for some reason is not to be included in the pre-encodedmedia asset or during a replay of the live event may be removed.Alternative audio segments may be referenced with muted audio in casesomething was said in the live event that needs to be removed from thepre-encoded media asset or replay of the event. Indictors for the creditstart and end may be inserted if not included in the original eventairing. Further, overlay indicators may be inserted or removed if notincluded or improperly included in the original event airing.

At 508, a defined range of the one or more media segments may beselected, extracted, and decrypted for additional one or more editsthrough the interface. In accordance with an embodiment, the Live toOn-Demand toolkit system 117 may be configured to select, extract, anddecrypt the defined range of the one or more media segments foradditional one or more edits through the interface. In such case, uponviewing by a human or machine, the defined range of media segments maybe selected for additional editing beyond the capabilities of simplemanifest manipulation.

The selected, extracted, and decrypted defined range of the one or moremedia segments may correspond to the highest quality profile and may becombined into a file format that correspond to one or more of a singlevideo file, a single audio file for each audio track, and a singlecaption file for each supported language in case of a preferred fileformat over the one or more media segments in the defined range. TheLive to On-Demand toolkit system 117 may download the file format forthe defined range and edit locally or remotely based on a video editingprogram, and submit the edited file through the content processingsystem 121 and moved to the content delivery system 160. The edited andprocessed media segments may be referenced in place of the originalmedia segments in the pre-encoded media asset for the archived livecontent. In accordance with an embodiment, the Live to On-Demand toolkitsystem 117 may be further configured to encode the edited one or moremedia segments and package to match specifications of the live inputstream.

At 510, the manifest of the modified pre-encoded media asset for a liveevent may be indexed as a new pre-encoded media asset and made availablefor a playback, a delayed playback in the live input stream, or are-play of the live event in the disparate live media output stream. Inaccordance with an embodiment, the indexing and storage system 148 maybe configured to index the manifest of the modified pre-encoded mediaasset for a live event as the new pre-encoded media asset and madeavailable for a playback, a delayed playback in the live input stream,or a re-play of the live event in the disparate live media outputstream.

At 512, the manifest of live input stream may be manipulated based onidentified one or more media segments. In accordance with an embodiment,the stream publishing engine 150 may be configured to manipulate amanifest of the generated pre-encoded media asset for the live event toreplace references to the original one or more media segments with thenewly created edited one or more media segments. The manifest may bemanipulated due to one or more factors. For example, the manifest may bemanipulated for a removal of references to the one or more mediasegments prior to a live event start indicator and after a live eventend indicator. The manifest may be manipulated to maintain indicatorsthat mark locations of a non-programming content and removal of durationinformation and at least one referenced media segment that correspondsto originally schedule non-programming content. The manifest may bemanipulated when the duration of the non-programming content is definedwhen generated pre-encoded media asset is played back or repeatedlyplayed back. The manifest may be further manipulated based on insertionof one or more indicators that mark a location of a live event start andend and removal of references to the one or more media segments prior tothe live event start and after the live event end in case the capturewas based on a scheduled time that was inaccurate or an indicator whichmarks that the live event start or end was missed. The manifest may befurther manipulated to insert the one or more indicators that marklocations of non-programming content and a removal of the referenced oneor more media segments for originally scheduled non-programming contentin case an indicator for a non-programming content was missed. Themanifest may be further manipulated for a movement of an indicator thatmarks an event if was inaccurately aligned with media content andremoval of the references to a desired media segment based on a newlocation of the event indicator. The manifest may be further manipulatedto facilitate removal of the references to the one or more mediasegments that are to be excluded in the generated pre-encoded mediaasset, a delayed play of the live event, or a replay of the live event.The manifest may be further manipulated for a replacement of originalaudio media segments with alternative audio media segments. Thealternative audio media segments may correspond to segments with mutedaudio if a portion of an audio content is to be excluded in thegenerated pre-encoded media asset, a delayed play of the live event, ora re-play of the live event. The manifest may be further manipulated tofacilitate an insertion or a movement of the one or more indicators thatmark graphical treatment if originally unmarked or improperly alignedwith the media content in the live input stream.

At 514, the encoded and packaged one or more media segments may bepublished to the media storage 162 on the content delivery system 160 togenerate pre-encoded media asset for repeated playback based onmanipulation of manifest of live input stream. In accordance with anembodiment, the stream publishing engine 150 may be further configuredto publish the encoded and packaged one or more media segments to themedia storage 162 on the content delivery system 160. Accordingly, apre-encoded media asset for repeated playback based on manipulation ofmanifest of live input stream may be generated.

In accordance with an embodiment, the stream publishing engine 150 maybe configured to generate a preview of live input streams based oninsertion of a new segment from a scheduled manifest of the live inputstream into a preview manifest of the live input stream on an intervalnot greater than previous media segment duration. The preview of thelive input stream is generated based on a low-latency protocol duringoriginal encode of the live input stream. For the preview of live inputstreams, the stream publishing engine 150 may be further configured tocreate a custom manifest to individually address a Group of pictures ora Sub-group of pictures within a media segment that allows a mediaplayer of a consumer device to operate closer to a live point of a liveinput stream. In accordance with an embodiment, for the preview of thelive input streams, a custom player may be created to operate with ashorter buffer and operate closer to a live point of a live inputstream.

The stream publishing engine 150 may be configured to determineinsertion of a next media segment to the disparate live media outputstream manifest based on the generated updated schedule. The generatedupdated schedule may indicate one or more of insertion of anon-programming content indicator and trafficked non-programming contentfor a specified duration of a non-programming content break, andinsertion of the non-programming content indicator and filler contentfor the specified duration of the non-programming content break whichallows a consumer device to replace the filler content with targetednon-programming content. The generated updated schedule may indicate aswitch to an alternate live input stream due to one or more of:technical defects, a live event ended on a current live input streamahead of scheduled time, or a provision of a different vantage point forthe live event. The generated updated schedule may indicate insertion offiller program content as a first live event ended before scheduled timeand the next event has not yet started. The generated updated schedulemay further indicate a start of the next event ahead of schedule if thefirst live event ended early, a delay to switch to a next scheduled liveinput stream or a pre-encoded media asset if current live event runs fora time period that exceeds a threshold time period, insertion of agraphical treatment indicator to be inserted at the consumer device, andinsertion of a programming content indicator to mark a beginning or anend of a live event in the disparate live media output stream manifest.

Themanipulation of the manifest may further correspond a movement of anindicator that marks an event if was inaccurately aligned with mediacontent and removal of the references to a desired media segment basedon a new location of the event indicator, removal of the references tothe one or more media segments that are to be excluded in the generatedpre-encoded media asset, a delayed play of the live event, or a replayof the live event, a replacement of original audio media segments withalternative audio media segments, and/or insertion or a movement of theone or more indicators that mark graphical treatment if originallyunmarked or improperly aligned with the media content in the live inputstream. The alternative audio media segments may correspond to segmentswith muted audio if a portion of an audio content is to be excluded inthe generated pre-encoded media asset, a delayed play of the live event,or a re-play of the live event.

In accordance with an embodiment, the Live to On-Demand toolkit system117 may provide an interface to select, extract, and decrypt a definedrange of the one or more media segments for additional one or moreedits. The selected, extracted, and decrypted defined range of the oneor more media segments corresponds to the highest quality profile andcombined into a file format that correspond to one or more of a singlevideo file, a single audio file for each audio track, and a singlecaption file for each supported language in case the one or moreprocessors prefer the file format over a plurality of individual mediasegments in the defined range. The Live to On-Demand toolkit system 117may be configured to download the file format for the define range andedited locally or remotely based on a video editing program. Inaccordance with an embodiment, the edited one or more media segments maybe encoded and package to match a specifications of the live inputstream. Further, the encoded and packaged one or more media segments maybe published by the stream publishing engine 150 to the media storage162 on the content delivery system 160.

In accordance with an embodiment, the Live to On-Demand toolkit system117 may be configured to modify a manifest of the generated pre-encodedmedia asset for a live event to replace references to the original oneor more media segments with the newly created edited one or more mediasegments. Accordingly, the stream publishing engine 150 may publish themanifest of the modified pre-encoded media asset for the live event tothe media storage 162 on the content delivery system 160.

In accordance with an embodiment, the manifest of the modifiedpre-encoded media asset for a live event may be indexed by the indexingand storage system 148 as a new pre-encoded media asset and madeavailable for a playback, a delayed playback in the live input stream,or a re-play of the live event in the disparate live media outputstream.

Various embodiments of the disclosure may provide a computer-readablemedium, such as the non-transitory computer-readable medium 606, havingstored thereon, computer implemented instruction that when executed bythe processor 604 causes the media packaging and distribution system 102to execute operations for publishing a disparate live media outputstream that complies with distribution format regulations. In accordancewith an embodiment, the processor 604 causes the stream playout anddistribution system 112 in the media packaging and distribution system102 to execute operations to generate a preview based on a low-latencyprotocol for a plurality of live input streams. In accordance with anembodiment, the plurality of live input streams may include additionalaudio content that identifies location and duration of a non-programmingcontent for live events that correspond to the plurality of live inputstreams. One or more media segments of a live input stream of theplurality of live input streams are edited based on manipulation of amanifest of the live input stream.

The processor 604 causes the VPC system 115 to execute operations togenerate an updated schedule based on one or more events identified inthe preview of live input streams in real-time. The updated schedule mayinclude one or more transitions between the plurality of live inputstreams and a plurality of pre-encoded media assets. The streampublishing engine 150 may be configured to generate a disparate livemedia output stream manifest based on manipulation of manifests of theplurality of live input streams and the plurality of pre-encoded mediaassets in accordance with the updated schedule. The generated disparatelive media output stream manifest may be delayed to allow decisionsbased on the previewed live input streams in a disparate live mediaoutput stream. The generated disparate live media output stream manifestmay correspond to a disparate live media output stream. The disparatelive media output stream may include programming content andnon-programming content available to the one or more processors forimmediate consumption. The disparate live media output stream complieswith distribution format regulations.

Typically, in the broadcast industry, production control systems areutilized to allow an operator to switch between live input streamsreceived from live sources, play pre-encoded media assets, such as VODassets, insert and trigger non-programming content, and insert graphicaltreatment, such as network and program rating bugs. Further, for sourceswithout embedded closed captions, the production control systems alsosupport providing an audio feed to an operator, such as a stenographer,for creation and insertion of the closed captions. The output of suchproduction control systems are referred to as a fully produced feedready for distribution.

However, such production control systems require the live sources to beaggregated at a central location, so that the production control systemscan decode corresponding live input streams into baseband forprocessing. The aggregation and decoding is essential in case of liveinput streams as corresponding schedules tend to change owing to variousreasons, such as when live events or programs end early or run long.Such systems require all the content to be backhauled, encoded, decoded,and then re-encoded at different times. In case of the pre-encoded mediaassets, fast switching may be required between the redundant broadcastair chains in case of a failure. But, this approach is expensive and istherefore suited for such channels that can attract large audiences tojustify the cost.

Leveraging an understanding of modern web streaming protocols, the mediapackaging and distribution system 102 may virtualize the productioncontrol functions, eliminating the need to aggregate and decode the livesources at a central location, and continue reduction in latency forsuch protocols. Thus, not everything has to come back to a centralcontrol location, get decoded and processed. An operator is providedwith a view of the available live sources slightly ahead of the endconsumer. The operator may then in real-time adjust the schedule tocontrol switching between the various live input sources and On-Demandcontent including ads, as well as insert ad and overlay indicators intothe live output manifest. The switches may be executed simply bymanipulating the text-based live output manifest based on instructionsfrom the operator. Content is allowed to be published to a contentdelivery system and leverage manifest manipulation, perform switching,using an extra manifest with closed captions and insert the manifest tovideo content. Thus, a new manifest may be created with closed captionsbased on other streams, like live-to-live streams and VOD-to-livesignals, at the client side.

Because the media content itself does not need to be processed beyondthe initial creation of the live streams and pre-encoded media assetsprepared for web distribution, it is extremely inexpensive to provide afully produced output feed. It is based solely on the cost to manipulatethe text-based manifests, which provide the instructions for thereceivers or consumer devices to execute. The system can supporttargeted ad insertion at the receiver or individual consumer devicesthrough the insertion of tags in the live stream manifest. It furtherleverages the processing power of the receivers and consumer devices toinsert targeted channel graphics and overlay advertisements andpromotions.

The switch time between the live sources is equal to the duration of theadaptive bit rate segment, which over the past few years has decreasedfrom 10 seconds to 2 seconds and will continue to reduce over time, forexample half-a-second. The media packaging and distribution system 102facilitates the switch latency to continue to decline with the segmentduration due to enhanced performance of the content delivery system. Incertain examples, for example, sports gambling, latencies are furtherrequired to be dropped.

The VPC system 115 may archive live programs, for example Olympics beingbroadcasted from a foreign location as live stream in another time zone,for an event replay at a desired time, for example 2-3 hours later. Inaddition to archiving the program as a pre-encoded media asset, themedia packaging and distribution system 102 may mark the location of thead breaks while removing the underlying content for the duration of thebreak, so said breaks can be eliminated, reduced in duration, orextended in duration when the asset is replayed.

Finally included in the Live to On-Demand toolkit is the functionalityto edit portions of the archived content prior to replay. Editing may bedone to simply remove some of the referenced video and audio segmentsfrom the manifest if something happened in the live show that should notbe included in the replay, to replace some of the audio segments withmuted audio if something was said during the live broadcast that needsto be removed, or to download and edit a short sequence of video andaudio segments, submit only that portion of the asset to the contentprocessing system, and then edit the manifest to reference the editedsegments. For example, in case of a Live baseball game, if a playerflips off, a fan wouldn't like to watch the same. Thus, the Live toOn-Demand toolkit may facilitate such segments to be removed from thebroadcast content.
